I rekomen DH for farming... I built one for 13million... very fair dps and tankabIlity... for few more million I could easily get higher dps and some lifesteal.

basically for the low prices you could gear up all other classes fairly decently but generally I feel DH very good for speed farming as they can clear creeps very fast and vault around the whole map quickly... although for an all rounder I think barb best
